As mentioned at KWLUG, I'm enjoying the openstreetmap.org project. If you have an interest in Maps, GPS, geocaching, GIS or other location related activities you will find this project interesting.
"OpenStreetMap is a project aimed squarely at creating and providing free geographic data such as street maps to anyone who wants them. The project was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive or unexpected ways."
You can support OpenStreetMap.org by making a paypal donation by contributing code and / or data and / or gps devices for use by other members.
